About this document
Direct Active Shift Control in Transmissions by Vlad Sibiceanu is a document available to read on EtoBox.
This document introduces a new scheme for fully electronic control of automatic transmissions called Direct Active Shift Control (DASC). DASC uses proportional control solenoid valves to independently control the pressure of each friction element without any passive hydraulic or mechanical components. The document first reviews control systems from older hydro-mechanical to modern electro-hydraulic systems. It then introduces the concept of DASC and discusses actuator performance. Finally, it shows simple t
